[PATCH] devargs: Fix crash due to global devargs uninitailization from secondary process

[madhuker.mythri at oracle.com]

From: Madhuker Mythri <madhuker.mythri at oracle.com>

Failsafe pmd started crashing with global devargs syntax as devargs is
not memset to zero. Access it to in rte_devargs_parse() resulted in a
crash when called from secondary process.
